Extractor of secrets from PM on TV (6)
I believe the answer is:
hacker
'pm on tv' is the definition.
(I've seen this before)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for hacker that I've seen before include "Modern criminal who breaks into computers" , "potentially a threat to security" , "Modern burglar who breaks in to computer systems" , "One imposing cuts" , "Modern criminal who breaks into computer systems" .)
